The way of Congregational churches cleared : in two treatises. In the former, from the historical aspersions of Mr. Robert Baylie, in his book, called, A disswasive from the errors of the time. In the latter, from some contradictions of Vindicæ Clavium : and from, some mis-constructions of learned Mr. Rutherford in his book intituled The due right of presbyteries. / By Mr. John Cotton, sometime preacher at Boston in Lincoln-shire, and now teacher of the Church at Boston, in New-England.
